To upgrade to 383 or not?
 

I have embarked on a rebuild project that started as replacing the opti-spark and is now totally out of control :D

After taking all the top-end and front off leaving the short block, the engine builder mentioned I have come this far I should pull the engine hone block, replacerings, and oil pump.

However, I am considering installing a 383 package, has anyone done this? What kind of HP increase going to the 383 vs 350?

So far here is where I'm at in my quest to freshen up my engine;
